Improved Fred Locke insulator

Improved Insulator.

On June 7 letters patent were issued to Fred M. Locke, Victor, N. Y., on an improved insulator. The object Mr. Locke had in view in designing this insulator was to prevent leakage of the current from the wire over the insulator to the support, thereby obviating the burning off of the pin. This is accomplished by providing the insulator with a long central petticoat, which encloses the supporting pin down to a point adjacent to the cross arm, and by making it small in diameter in proportion to the petticoats of the insulator above it. The burning off of pins where high voltage currents are transmitted has rendered necessary some means of preventing this leakage, and this Mr. Locke claims can be accomplished by the extension of the inner petticoat in the manner described, thus providing a protecting sleeve for the pin and increasing the arcing distance of the current around the insulator.
